Some teachers travelled to school by car. The table shows the number of teachers in the cars.
\begin{tabular}{|c|c|}
\hline $\begin{array}{c}\text { Number of teachers } \\
\text { in one car }\end{array}$ & Number of cars \\
\hline 1 & 3 \\
\hline 2 & 4 \\
\hline 3 & 6 \\
\hline 4 & 2 \\
\hline
\end{tabular}
a) What was the modal number of teachers in a car?
b) What was the median number of teachers in a car?
c) What was the mean number of teachers in a car?
Answer
\(\boxed{\text{Modal} = 3, \text{Median} = 3, \text{Mean} \approx 2.47}\)
Step 1 ：Find the mode by looking at the highest number of cars for a given number of teachers in one car: \(\text{Mode} = 3\)
Step 2 ：Find the median by ordering the dataset and finding the middle value: \(\text{Median} = 3\)
Step 3 ：Find the mean by dividing the total number of teachers by the total number of cars: \(\text{Mean} = \frac{37}{15} \approx 2.47\)
Step 4 ：\(\boxed{\text{Modal} = 3, \text{Median} = 3, \text{Mean} \approx 2.47}\)
